"I owe it to our student-athletes to provide them with the best conditions for success, both on and off the field, and I am committed to hiring coaches who will develop our players to their fullest potential," Dykes said in a statement.

Dykes is expected to hire a defensive coordinator soon, someone with "significant experience in that role who can lead our defensive unit to success in one of the most prolific offensive conferences in the country," he said in the statement.

Dykes might consider a man with previous experience as a defensive coordinator at Cal in Clancy Pendergast who was on Jeff Tedford's staff from 2010 through '12. Pendergast, USC's defensive coordinator in 2013, has extensive experience game-planning against Pac-12 offenses.

Cal's defense, depleted by injuries to front-line players as it was, nevertheless was historically bad in 2013.

The Bears allowed the most points in school history, 551, a figure that ranked 122nd out of 123 FBS schools last year.

Buh's defense was next-to-last in yards allowed per game at 529.6 and last in passing yards allowed per game, 341. Figures for points, total yards and passing yards allowed by Cal in 2013 were the worst in 130 years of Cal football.
